Abstract
Description
- The present invention relates to generally to barriers, and more specifically to barriers that are convenient for quickly finding a correct installation method.
- Often, in order to prevent children or pets from leaving a room, or entering/exiting a specific place, a removable passage barrier is installed between two locations, such as between two door jambs of a doorway.

- When an element is referred to as being “fixed to” or “disposed on” another element, it can be directly connected to the other element or indirectly connected to that element. When an element is said to be “connected to” another element, it can be directly connected to the other element or indirectly connected to that element.
- The terms “length”, “width”, “upper”, “lower”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer” and other indications of the orientation or positional relationship are based on the orientation or positional relationship shown in the figures, and are only for the convenience of describing the fasteners and passage barriers, and simplifying the description, rather than indicating or implying that the device or element must have a specific orientation, be constructed and operated in a specific orientation.
- The terms “first” and “second” are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined with “first” and “second” may explicitly or implicitly include one or more of these features. In the description, “multiple” means two or more than two, unless otherwise specifically defined.
- Turning to
FIGS. 1, 2 and 3 , the passage barrier is designated by thereference numeral 100. Thepassage barrier 100 generally includes a substantially “right-angled U-shaped”frame 20 comprising afirst side frame 22, asecond side frame 23, and ahorizontal side frame 24, and adoor 30 that is pivotally engaged in theframe 20. Theframe 20 has four corners, with each of the corners having anouter end 21, and theouter ends 21 having amounting hole 25 for slidingly receiving a pressurizedfastener 10. The pressurizedfastener 10 comprises ascrew 11, which includes a disk-shaped head 13 fixed at an end and arod 14 with an external thread. Thehead 13 is configured to abut against, and apply pressure to, walls or door jambs on both sides of a passage, and therod 14 is slidably received in themounting hole 25. The pressurizedfastener 10 comprises anadjustment member 12 which has a throughhole 121 with an internal thread. The throughhole 121 accepts part of therod 14 and is rotatable around arotation axis 1211. The external thread on therod 14 is engaged with the internal thread of thethrough hole 121. In use a hand or a tool turns theadjustment member 12 toward theouter end 21 and makes contact with theouter end 21, and when theadjustment member 12 continues to travel in the direction of theouter end 21, this travel will cause thescrew 11 to slide outward, and causes thehead 13 exert pressure on the walls or door jambs on both sides of the passage. - The
adjustment member 12 may optionally include a plurality of evenly distributednotches 122, and thenotches 122 may be used for accepting a wrench or other tools. The wrench or other tools may be detachably inserted into any one of thenotches 122 and may be used to drive theadjustment member 12 to rotate by applying force. While one embodiment of the pressurizedfastener 10 is illustrated inFIGS. 1 and 2 , other embodiments, such as any one of the pressurized fasteners shown inFIGS. 4, 5, 7, 9, 10, 12 , may be substituted and while one embodiment of the mounting hole is illustrated inFIG. 1 . Other embodiments of the mounting hole may be substituted, for example any one of the mounting holes shown inFIGS. 6, 8, 11, 14 , which correspond to a chosen pressurized fastener. -
FIGS. 4 and 5 show another embodiment of apressurized fastener 101 that may be used in the base structure ofFIG. 1 (the illustration of the adjustment member is omitted because the adjustment member is the same as that in the base structure) andFIG. 6 shows amounting hole 251. The pressurizedfastener 101 includes ahead 131 and arod 141. The outer surface of therod 141 includes a first threadedpart 142, a second threadedpart 143, a first non-threadedpart 144 and a second non-threadedpart 145. Among them, the threaded part and the non-threaded part are alternately connected, and a dividing line between the threaded part and the non-threaded part lies on a circumferential surface of a virtual cylinder with the rotation axis of the adjustment member as the cylinder axis. Among them, the first threadedpart 142 and the second threadedpart 143 are located on the circumferential surface of the virtual cylinder, and the firstnon-threaded part 144 and the second non-threadedpart 145 are the opposite sides of a regular quadrangle prism with edges (such as edges a, b, c and d inFIGS. 4 and 5 ) arranged on the circumferential surface of the virtual cylinder, and edges a, b, c and d are the dividing lines between the threaded part and the non-threaded part. It should be understood that in this embodiment, the side lengths of opposite sides (e.g., side e and side f inFIG. 4 ) of the bottom surface of the regular quadrangle prism are not limited, and different sizes can be adopted as needed, and the selected sizes determine the area sizes of the first threadedpart 142 and the second threadedpart 143. For example, the longer the side e and the side f the smaller the area of the first threadedpart 142 and the second threadedpart 143, otherwise, the larger the area. - As shown in
FIG. 6 , a cross-sectional shape of themounting hole 251 is substantially the same as that of therod 141, but the size is slightly larger than that of therod 141 and the inner surface of themounting hole 251 is unthreaded, so that therod 141 can slide in themounting hole 251 and can be prevented from rotating in themounting hole 251. -
FIG. 7 shows another embodiment of a pressurizedfastener 201 andFIG. 8 shows amounting hole 351. The pressurizedfastener 201 includes ahead 231 and arod 241. The outer surface of therod 241 includes a threadedpart 242 and anon-threaded part 243. The dividing line between the threaded part and the non-threaded part lies on a circumferential surface of a virtual cylinder with the rotation axis of the adjustment member as the cylinder axis, wherein the threadedpart 242 lies on the circumferential surface corresponding to a major arc of the virtual cylinder, the non-threadedpart 243 is a plane connecting two edges of the threaded part 242 (such as edge p and edge q inFIG. 7 ), and edge p and edge q are the dividing lines between the threaded part and the non-threaded part. It should be understood that in this embodiment, the length of the major arc (such as the major arc g inFIG. 7 ) is not limited (unless unrealistic), and different sizes can be adopted as needed, and the selected size determines the area of the threadedportion 242. For example, the longer the major arc g is, the larger the area of the threadedpart 242 is, and vice versa. It is not recommended that the threadedpart 242 is lies on a circumferential surface corresponding to a semi-circular arc or a minor arc in this embodiment, because this will cause the adjustingpart 12 to shake in the mountinghole 351 when rotating, resulting in that the internal thread of the adjustment member cannot well engage the external thread of the threadedpart 242. It should be understood that thenon-threaded part 243 can also be an arc surface or other irregular surface which connects two edges of the threaded part 242 (such as edge p and edge q inFIG. 7 ) and is within the circumferential surface of the virtual cylinder. - As shown in
FIG. 8 , a cross-sectional shape of the mountinghole 351 is substantially the same as that of therod 241, but the size is slightly larger than that of therod 241 and the inner surface of the mountinghole 351 is unthreaded, so that therod 241 can slide in the mountinghole 351 and can be prevented from rotating in the mountinghole 351. -
FIGS. 9 and 10 show another embodiment of apressurized fastener 301 andFIG. 11 shows a mountinghole 451. Thepressurized fastener 301 includes ahead 331 and arod 341. The outer surface of therod 341 includes a first threadedpart 342, a second threadedpart 343, a firstnon-threaded part 344 and a fourthnon-threaded part 345. Among them, the threaded part and the non-threaded part are alternately arranged, and the dividing line between the threaded part and the non-threaded part is located on the circumferential surface of a virtual cylinder with the rotation axis of the adjusting member as the cylinder axis. Among them, the first threadedpart 342 and the second threadedpart 343 are located on the circumferential surface of the virtual cylinder, and the firstnon-threaded part 344 and the secondnon-threaded part 345 are two opposite sides of a straight prism whose edges (such as edge h, edge i, edge j and edge k inFIGS. 9 and 10 ) are arranged on the virtual cylindrical surface and the bottom surface is trapezoidal, which can be the sides corresponding to two waists of a trapezoid or the sides corresponding to the upper and lower bottoms of the trapezoid. It should be understood that in this embodiment, the lengths of two opposite waists (such as waist 1 and waist m inFIG. 9 ) at the bottom of the straight prism are not limited, and different lengths can be adopted as needed. The selected lengths determine the area sizes of the first threadedpart 342 and the second threadedpart 343. For example, the larger the lengths of waist 1 and waist m, the smaller the area of at least one of the first threadedpart 342 and the second threadedpart 343, and vice versa. It is not recommended that the upper bottom and the lower bottom of the trapezoid be located on the same side of the cylinder axis, because this will cause the adjusting member to shake in the mountinghole 451 when rotating, resulting in that the internal thread of the adjusting member cannot well engage the external thread of the first threadedpart 342 and the second threadedpart 343. - As shown in
FIG. 11 , a cross-sectional shape of the mountinghole 451 is substantially the same as that of therod 341, but the size is slightly larger than that of therod 341 and the inner surface of the mountinghole 451 is unthreaded, so that therod 341 can slide in the mountinghole 451 and can be prevented from rotating in the mountinghole 451. -
FIGS. 12 and 13 show another embodiment of apressurized fastener 401 andFIG. 14 shows a mountinghole 551. Thepressurized fastener 401 includes ahead 431 and arod 441. The outer surface of therod 441 includes a first engaging threadedpart 442, a second engaging threadedpart 443, a third engaging threadedpart 444, a first non-engaging threadedpart 445, a second non-engaging threadedpart 446 and a third non-engaging threadedpart 447. Among them, the thread of the engaging threaded parts can be engaged with the internal thread of the adjustment member, while the thread of the non-engaging threaded parts cannot be engaged with the internal thread of the adjustment member. Engaging threaded parts and non-engaging threaded parts are alternately arranged, and the dividing line between the engaging threaded part and non-engaging threaded part is located on the circumferential surface of a virtual cylinder with the rotation axis of the adjustment member as the cylinder axis. Among them, the first engaging threadedpart 442, the second engaging threadedpart 443 and the third engaging threadedpart 444 are annularly arranged on the circumferential surface of the virtual cylinder, and the first non-engaging threadedpart 445, the second non-engaging threadedpart 446 and the third non-engaging threadedpart 447 are convex circular arc surfaces which are respectively connected between the two engaging threaded parts and are located in the circumferential surface of the virtual cylinder, so that the engaging threaded part and the non-engaging threaded part make a substantially smooth transition connection, and their threads are continuous. It can be understood that the number of engaging and non-engaging threaded parts can be selected according to requirements, for example, it can be two engaging threaded parts and two non-engaging threaded parts. It should be understood that the number of engaging threaded parts and non-engaging threaded parts can also be four or five. However, the number cannot be increased indefinitely, and the selected number should make the cross section of therod 441 appear obviously non-circular. It can be understood that the above-mentioned non-engaging threaded part can also be replaced by a flat or convex arc surface or concave arc surface or other irregular surface non-threaded part. - As shown in
FIG. 14 , a cross-sectional shape of the mountinghole 551 is substantially the same as that of therod 441, but the size is slightly larger than that of therod 441 and the inner surface of the mountinghole 551 is unthreaded, so that therod 441 can slide in the mountinghole 551 and can be prevented from rotating in the mountinghole 551. - Some of the features in the above embodiments can be combined to form new embodiments, for example, in one embodiment, some of the non-engaging parts can be flat, some of them arc-shaped, or some of the non-engaging parts can have threads, some of them have no threads, and so on.
- The above embodiments improve the pressurized fastener and the mounting hole, so that the pressurized fastener can slide in the mounting hole but cannot rotate, thus preventing the installer from mistaking the installation operation by screwing the pressurized fastener when installing the passage barrier, thus leading the installer to give up screwing the pressurized fastener and install by rotating the adjustment member, and facilitating the installer to quickly find the correct installation method.
- The above descriptions are only preferred embodiments and are not intended to limit the disclosure. Any modification, equivalent replacement and improvement made within the spirit and principle of the disclosure shall be included in the scope of protection of the disclosure.
